Sentry Crash Report:

Description Olaf Piesche 2009-12-26 21:55:12 UTC 
Application: digikam (rc..-rc)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
Starting digikam on KDE SC 4.4 beta 2 on Kubuntu karmic. Crashes almost everytime on scanning directories, sometimes (1/20) it starts but then crashes shortly afterwards during image editing (possibly a different bug, will report when I get it again). Kubuntu packages are a bit broken at the moment, but I've gotten things to work by removing libkdcraw7, libkipi6 and kipi-plugins, then running digikam with libkdcraw8 and libkipi7. 
I can run this through gdb and provide more information if necessary.

The crash can be reproduced everytime.

 -- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
